Grant your conversational AI (like Claude or Cursor) the power of a dedicated German accounting clerk. The sevDesk MCP transforms your LLM into a sophisticated financial nexus capable of creating invoices, querying past-due credit notes, recording vouchers, and tracking your CRM endpoints dynamically. Stop wrestling with browser-based accounting dashboards and let your AI manage your bookkeeping automatically.

What you can do

  • Client & Supplier CRM Mastery — Read the entire client database via list_contacts, retrieve detailed metadata for specific IDs (get_contact), or seamlessly register brand new vendors via create_contact
  • Autonomous Invoicing & Orders — Fetch paginated ledger lists using list_invoices or list_orders, and delve deep into line items, calculated taxes, and due statuses directly using get_invoice and get_order
  • Inventory & Service Architecture — Monitor available billable components via list_parts, inspect standard pricing, and introduce novel catalog options autonomously via create_part
  • Accounting Governance — Keep strict tabs on your chart of accounts with list_accounting_types while verifying associated business inlets securely using list_bank_accounts
  • Voucher & Credit Auditing — Consolidate physical receipts through list_vouchers and trace structural adjustments flawlessly by scanning list_credit_notes

How it works

  1. Install this module directly into your MCP-compatible IDE or conversational context
  2. Establish the secure connection effortlessly by injecting your 32-character hexadecimal sevDesk API Token
  3. Engage your AI explicitly: "What's the net total on invoice #392911, and who is the attached client?"

Who is this for?

  • Freelancers & Solopreneurs — quickly ask your agent to draft new customer records and extract pending invoice tallies without leaving the editor
  • Financial Auditors — instruct the AI to cross-reference registered parts and orders against generated credit notes natively
  • Agency Managers — effortlessly check current bank configuration parameters and available accounting categories entirely via conversational prompts

Extract the details of invoice #18742 and summarize its line items alongside the associated contact name.

Invoking `get_invoice` using ID 18742 successfully queried the sevDesk API endpoint. The underlying contact reference resolves beautifully to the recognized entity "Stark Industries". Inspecting the associated line-item array reveals two dominant artifacts currently billed: Software Maintenance Support (15 units representing hourly increments at 120.00 each) and Cloud Expansion Licensing Cost (a flat 400.00 fee). The overall net calculation indicates 2200.00 EUR dynamically computed without outstanding adjustments. Do you wish to verify its status in `list_credit_notes` to rule out refunds?

List all currently existing bank accounts natively integrated using the core config.

Running the targeted diagnostic `list_bank_accounts` extracted exactly 2 live inlets formally structured under this tenant entity. Check account 001 maps to the primary 'Deutsche Bank GmbH' with an active balancing status indicating ready-reckoner liquidity. Setup inlet 002 flags explicitly as the secondary 'Commerzbank Corporate Node' reserve. Both objects exhibit identical local currency encodings (EUR).

Yes contextually. When you execute the `create_contact` function natively alongside `category` parameters (`3` stands for customer, `4` for typical suppliers), sevDesk anchors these entries officially inside the identical primary table. Be clear about whether it's an email-lead versus a firm.
